To all whom it may concern:

lie it known that we, HENRY A. l/Vrsn Woo!) and CONRAD Nonnrons,citizens of the United States, said WOOD residing at New York, in thecounty of New York and State of New York, said Nonnrons residing atJersey City Heights, county of Hudson, and State of New Jersey, haveinvented a new and useful Folding and Collecting Q Mechanism, of whichthe following is a.

specification.

This invention relates to a folding delivery in which one of thecylinders thereof is adapted to out, fold and deliver a sheet on eachrevolution from a continuous web, or to collect on alternaterevolutions, so as to deliver the successive papers folded in pairs. Theprincipal objects of the invention are to provide an exceedingly simplearrangement for effecting the change, and more specifically, anarrangement in which the change is made simply by fixing a gear againstrotating and rendering another gear inoperative,or vice versa; toprovide for operating the piercing points of the cutting and collectingcylinder from the rotary car rier or delivery cylinder when it isdesired to collect, and to operate said pins from a stationary memberwhen it is desired to operate without collecting; also to provide improvements in details of the mechanism for operating the pins andimproved means whereby one of the sets of grippers on the deliverycylinder can be thrown out of operation conveniently to permit theirdelivering only once for each revolution of that cylinder. 4 Y Theinvention also involves improvements in details of construction andcombinations of parts as will appear.

Reference is to be had to the accompanying drawings in which,

Fig. 8 is a similar view showing the position of the parts at the nexthalf revolution of the collecting cylinder with the two sheets justready to be folded and taken away by the delivery cylinder.

The mechanism is shown as mounted on the frame A of a web printingmachine. In the form illustrated, the mechanism consists mainly of afolding, cutting and collecting cylinder B, and a rotary carrier ordelivery cylinder C. These cylinders are mounted on shafts 7 and 8,respectively, carried in hearings on the frame. The main driving geartrain, not shown, imparts power to a gear 9 on the shaft 8 which mesheswith a gear 10 on the shaft 7. These two gears bear the same relation toeach other, as to diameter, as the two cylinders, and consequently drivethe two cylinders at the same circumferential speed.

In the form shown, the cylinder B is half the diameter of the cylinder Cand consequently rotates twice to each rotation of the latter.

Th cylinder B is provided with the usual cutting knife 11, folding ortucking blade 12, and pin points 18,. These pin points are arranged in arow and adapted to reciprocate, and each one is operated by a gearsegment 14. These segments are mounted on a rod or shaft 15 which isadapted to escillate, and is provided with. a crank arm 16 provided witha pin 17 This pin operates in a hole in a circular ring 18. This ring isloosely mounted on the eccentrichub of a gear 19. This gear runs looseon the shaft 7. On the frame A is a bol-t21 which .is adapted to bemoved in so as to enter a depression formed. in aboss 20 on the face ofthe gear 19. When this is done, as shown in F 1;; 2, the gear 19 will beheld in stationary position. This is Q the condition required when thecylinder B is not collecting.-

291s provided in each crank lever 26 for On the shaft 8 isa gear 22 ofthe same diameter as the gear 19. This is designed to operate the gear19 when the bolt 21 is inoperative, to the dotted line position in whichit meshes with the gear 19.

Referringfnow to the rotary carrier or delivery cylinder .6, it will beseen that it is provided with two'setsof folding grippers 23 and 24..Each of the grippers consists of a roller mounted to oscillate on itsown end studs. The studs of the grippers 23 are mountedin hearings orboxes 25 forming part of the cylinder and of course movingtherewith. Onone end of this gripper is fastened a crank lever 26 which has aprojecting pin 27 operating in a groove of cam 28. This cam is fixed onthe frame A. To prevent the operation of the crank levers 26 by the cam.28 operating one pair of grippers when it is desired to collect, a setscrew holding it on the stud of the gripper. One

of these is simply loosened when it is desired 1 to silencea pair ofgrippers so as to permit this'crank lever to sw ng loosely on thegripper stud. This is done when the grippers ofthis setare held ininoperative position by meansof the spring pin 33. The other'end of thegripper or the stud with which it isprovidedat that end, has a gearseginent 30 meshing with. a similar gear segment 31 on the end of theother gripper 24; The gear segment 30 is provided with afprojection orboss 32 carrying a spring pin 33. On the face of one of the bearlng'[boxes 25 is a hole 34 into which the pin 33 is adapted to be projected,in order to render these grippers inoperative. One pair of grippers isordinarily silenced when collecting.

- The grippers 21operate in bearings 35 of a pair of bell-cranks 36.These bell-cranks are pivoted on studs .37 attached to the cylinder.They are provided with springs 38 to give the necessary flexible gripbetween the grippers. Adjustable stop screws 39 are mounted in puppets4O fastened to the cylinder C to regulate the necessary openings betweeneach pair of grippers.

I It isto be. understood that as we have shown the cylinder C of twicethe diameter of the cylinderB,the latter cylinder will rotate' twice foreach rotation of the former, and consequently there are two sets ofgrippers on the'cylinder' G and only one folding blade on thecylinder B.Whenfit is desired to dehvereverys'heet, the gear 19 is fixed instationaryposition by means of the bolt 21 "and the gear 22 is movedover to'the full line position of F ig. 2 where it will be inoperative.Furthermore, both sets of grippers of the cylinder C are left inoperative condition. In this case the operation of the cam ring 18causes the pin points 13 to be projected once during each revolution ofthe cylinder B and that at a time when the cylinder .0 is in theposition shown in Fig. 1. Thus the pins will have perforated the end ofthe web at this point at=the time at which the sheet in advance has justbeen severed. The pins are projected at this point and they are fullywithdrawn when the cylinder B has performed the half revolution from theposition shown in Fig. 1. In the latter position, theend of the web hasadvanced half way around the cylinder B and the tucking blade 12 is inposition to tuck the web in between the grippers 23 and 24. The twocylinders are in the relative position then indicated in Fig. 6, but thepin points at the top are not projected, as shown in that figure, butare withdrawn while the grippers 23 and 24 are swung outwardly ready togrip the sheet and fold it over the folding blade. On the next halfrevolution of the cutting cylinder B, the parts thereof are againbrought back-to the position shown in Fig. l. The grippers have carriedthe folded sheet away from the cutting'cylinder, the tail end of thesheet is just being severed by the cutting knife 11, and the leading endof the web has been punctured by the pin points, ready to repeat itsoperation.

In order to cause no unnecessary strain on the folded web while carriedfrom the folding point to the point at which the grippers begin to grip,the cam 28 is so constructed as to allow the grippers to remain in arelative stationary position from the point at which they grip the sheetfrom the cutting cylinder, to the point shown at the left in Fig. 1.From this point to the bottom of the delivery cylinder the grippers moveoutwardly, that is, they have an e ecting motion so that they can ejectthe bite of the sheet'and drop it on the conveyor belt 411. Thus thegrippers have a slight pulling-in motion, while the web is being tuckedin the bite between them, but that in'm'iedia-tely ceases and from thatpoint until the web is about to be ejected, they remain stationary.After this they comnience to eject the folded paper and drop it on thebelts. The rest of the rotation is an idle one, so far as any action bythese grippers on the sheet is concerned, but during that rotation theyare brought slightly inwardly so as to get them ready for pulling in thesheet when they againreach the tucking-in position at the top.

l/Vhen it is desired to collect two papers on the cylinder B and thendischarge them together, the pin bolt 21 is withdrawn from the gear 19,leaving it free to revolve, and

the gear 22 is moved along its shaft so as to mesh with the gear 19 andpositively drive it at the same speed as that of the shaft 8. The setscrew 2-9 connected with one of the grippers is loosened to render thatgripper imperative, and the sn'ing pin connected with the same pair ofgrippers is moved over into the hole 34:. This effectively renders thegrippers on one side of the delivery cylinder inoperative.

As the two gears 19 and have the same diameter, and as the cylinder Bhas half the diameter of the cylinder C, the gear 19 will rotate at halfthe speed, in revolutions per minute, of the cylinder B on the sameshaft. Consequently, the eccentric ring 18 will operate the piercingpins 13 only once for each 'two revolutions of the cutting cylinder B.Furthermore, the delivery cylinder will operate to deliver a sheet, orplurality of sheets, only once for each revolution, instead of twice, asin the case above scribed. Therefore, the operation will he place asindicated in the diagrammatic views, Figs. 5 to 8.

In the position shown inFig. 5, and also shown in Fig. 1, a sheet hasjust been severed and the leading end of theweb pierced by the pins. Nowupon the next half revolution of the cylinder B the pins are forcedfarther through the leading end of the web and it is taken half wayaround the cylinder. At this time the folding blade 12 is in foldingposition, but as the pair of grippers on the other cylinder which nowcome into registration with it have been rendered inoperative, nofolding action takes place. (See Fig. 6.)

On the next half revolution the sheet is drawn the rest of the wayaround the cylinder B and the pins project through the leading end ofthe web again, while the knife severs the web at this point. This isshown in Fig. 7.

The cylinder B then rotates another half a revolution, which causes thepins at the top to withdraw from the double thickness of paper whichthey have previously pierced. At the same time the opposite pair ofgrippers on cylinder C, which is in operative condition, comes intoregistration with the folding blade and receives the double foldtherefron'i. During the next half revolution the folded product iswithdrawn from the cutting cylinder and the parts reach the positionshown in Fig. 1 and are ready to start the collection of two moresheets.

It will be understood that although we have illustrated rid described amachine constructed for collecting only two sheets, yet the sameprinciples can be appliedw'he'n a larger ni'imher' of sheets are to becollected, a rid other cl'i'ang'es can be made in details ofconstiaiction without departing. from the scope of the invention asexpressed in the claims.
